im 20 yrs old and my boyfriend and i have unprotected sex at least 5 out of 7 days/week. i was expecting my period on the 13th, but on the 12th i had some brown spotting til the 16th and since then ive had either light pink spotting and very very light bleeding(pinkish). during the 16 days ive had this bleeding ive had two episodes of cramps that both lasted maybe about 5 min each. i was on birth control but went off about a couple months ago and took 2 emergency contraceptives about a month and a half ago. i thought i could have been pregnant so i took a hpt and it came out neg. please help me figure this out... thank you for taking the time to read this.
